Leaders at an Islamic summit on Thursday urged a dialogue between the Syrian opposition and regime just as a new initiative for talks proposed by an anti-government leader appeared to be unraveling.

Like previous diplomatic initiatives on Syria, opposition chief Mouaz al-Khatib’s call for talks made less than a week ago appeared doomed to failure. And with troops and rebels clashing for a second day around Damascus, frustrated Syrians dismissed the calls for dialogue as empty talk.

“All of this does not concern us,” said Iyad, a Syrian fighter on the outskirts of the capital Damascus, which has witnessed heavy fighting in the last two days.
